(C1. sag-197) Claims.

operations of routing a door for a lock or latch mechanism or of routing a door jamb for a bolt recess and striker plate. A further object of the invention is to provide a template adjustable to work on doors of diierent thicknesses, for example, on an outer door for which the standard thickness is usually one and three-quarters inches or an inside door having a thickness of one and three-eighths inches by ordinary standards. By this provision, it will be seen that one template may readily serve for mortising all the doors and jambs in the ordinary house, and greatly simplify and shorten the operation of installing door hardware.

In large scale housing construction, such as a real yestate sub-division in which ready built houses are offered for sale, a general contractor usually provides hardware of one style or make, and one template embodying my invention and of suitable style may be used throughout the subdivision on successive houses. However, a contractor building houses to individual specifications may have to install various types of door locks, and for that purpose I have provided a template constructed to permit alteration of the routing pattern and depth Iby substitution of -srnall parts and inserts.

Another object, achieved in the same manner as the foregoing, is to provide a template in which the parts immediately dening the routing pattern may be readily replaced if gouged or burred by the routing tool, thus saving the major portion of the template.

4In general terms I achieve the above objects of my invention and others which will be pointed out or be apparent as the following description of a preferred embodiment of my invention proceeds, by forming a template body having a 'rf-shaped opening for guiding a routing tool, in which the head of theT represents the area to be-,routed Ainmfqzirming the recess in the door to receive the lock mechanism and the recess in the jamb to receive the extended bolt or latch, and the stemofthe YVl represents the additional area tonbe routed in the jamb to receive the tongueof the striker; plate. `A sliding Agateis arraged'to cut off the T-stempart ofthe opening when the templateis `used on a' door. A kdepth plate is provided, conveniently hinged at oneside of the template and `having a like T-shaped opening, which may be swung into position over the template body to increase the thickness of the templateand thereby Yreduce the depth of the cut in adoor jamb. The face ofthe template which is to engage the work has spikes or spurs by which the template may loe'y temporarily secured to the woodwork, and gage arms are pivotally secured to both ends of the` template, to be swung into position toposit-the `template with relation to an edge ofthe Woodwork'as the thickness of the door may require.

Having .reference inow to the details of. the drawings, I have' shown .aitemplate comprising a body l0,l which'.Y in itspreferred form is built Vup in three layers and ,a depth plate ll hinged to one margin of the body. The lower layer of the body I0, appearing uncovered in portionsV of Fig. 2 andin profile in`Fig.J? is a face plate l2 having arflat 4nuten face suitable rforl application `to Va Plane serfeeeyof gegevens' ...et the! margin opposite to the hinges I3 is a rectangular opening I4 having its greatest length parallel to said margin and having a small rectangular extension I5 extending toward the hinged margin. The openings I4 and I5 have the configuration of the conventional striker plate and are made large enough to define the mortise required to set the largest striker plate which is likely to be used in conjunction with the particular template. The opening I5 represents the area to be mortised for the tongue of such striker plate.

The intermediate layer of the body I0, shown in Fig. 2, comprises two L-shaped plates I1, and two bars I8. The plates I1 extend from the ends of the face plate I2 to the opening I4 and from the distal margin of the face plate I 2 to the hinges I3. The plates of the hinges I3 which are secured to the plate I2 lie in the plane of the intermediate layer and may be considered parts thereof. The bars I8 extend along the hinged margin of the plate I2 convergently from the hinges I3 and are spaced by a gap I9. The space between the plates I1 and the bars I8 forms a guideway 20 upon the plate I2, in which is a gate 2|, arranged for sliding movement parallel to the bars I8. The gate 2| has an opening 22, which at one end of the movement of the gate will register with the opening I5, and it is manipulated by a handle 23 which extends through the gap I9. The gate 2I has the same thickness as the plates I1 and bars I8 and lies in their plane.

The inner layer of the body I8, shown exposed in Fig. l, has end plates 25, `preferably notched to expose the plates of the hinges I3, to.permit removal of the hingesandacenter plate 26 which has an opening A21 and an extension opening 28 registering with the openings I4 and I5 ofthe plate I2.

The xed elements of the three v.layers of the body IIJ are held together by screws 30, the plates 25 being thus secured to the plates I1 and to the face plate I2, and the plate 26being secured to the plates I1 and bars I8 and thence to the plate I2. f

The outer edge of the opening through the body II'I formed by the registering open-ings I4 and 21 and the gap between the plates I1 is closed by a bar 32, inlaid in suitable notches in the plates I2, I1, and 28'and secured by screws 33 to the plates I1. It will be observed that this general opening is bounded in the planes-of the intermediate andl inner layers by the relatively small individual plates I1Y and 26, by the gate 2 I, and by the bar 32. It is at these levels that damage by a routing tool is most apt to occur, and the construction comprising separable layers, each made of small parts, makes possible economical and veasily eie'cted repairs. Furthermore, since only the opening I4--I5 in the face plate I2 is bounded by fixed boundaries and as these boundaries are usually below the level of the guide of a routing tool, the size and shape of the general opening may be controlled within the limits of the opening I4I5 by substitution of differently shaped elements for the plates I1 and 26 and the gate 2I. The plates I1 and 26 and the gate 2 I may be considered as inserts for which substitution may be made either to effect repairs or to control the size and shape of the general opening.

The depth plate II also has an opening 35 corresponding to and registering with the opening I4-I5 Vas closed by the .bar 32. When the depth plate is folded over the body III. making a fourlayer template, the opening 35 will, like the opening III-I5, control the maximum size of the general opening, but the routing tool will be guided by the margins of the openings in the central layers. The depth plate I I also has a notch 36 in its proximal margin, disposed to register with the handle 23 of the gate 2I when the gate is in position to close the opening I5. The length of the handle 23 and the free space between the body I8 and the depth plate Il as provided by the hinges I3, are such that the handle 23 will engage the proximal margin of the depth plate at all positions other than the notch 36 when the depth plate is opened to the plane of the body I0 as shown in Figs. l and 2. This construction prevents the opening of the depth plate to the position indicated except when the gate 2I closes the opening I5.

To hold the gate 2| at either limit of its traverse in the guideway 20, the handle 23 is provided with a spring latch 38, illustrated in Fig. 8; Grooves 39 in the plate 26 extend from the opening 28 to the adjacent margin of the plate, to receive and hold the latch 38 at its limit positions, as shown in Fig. '1, it being understood as heretofore stated that the plate 26 is therein shown as if detached from the bars I8 and turned over and that the grooves 39 will engage the shown surface of the latch 38.

In order to aiix the template to woodwork, spurs 48 are provided. These-spurs are sharpened screws which pass freely through suitable holes in the plates 25 and I1 and are threaded in the face plate I2, from theworlring surface of which their sharp points extend. It will be seen that their degree of penetration into Woodwork is adjustable, and that when worn they may be removed for sharpening. They also serve, in com-` bination with the screws 30, to hold the plates 25 and I1 in orientation.

However, before the template is affixed to a door or a jamb by the spurs 40, it must be accurately placed relatively to the striker edge of the door or to the stop of the jamb. For this purpose, gage arms are provided at each end of the template. To place the template relatively to a door, a plurality of gage arms 42 may be mounted in individual slots 43 in the end margins of the body I2, and pivoted on pins 44 mounted in the plates I1 so as to swing to positions normal to the working face of the face plate I2. The gage arms 42 are sufficiently long to extend beyond Vther spurs 48 when they are normal to the plate I2 so that they may engage the side of 'a door while the spurs are merely pressed against the door edge without penetrating it. rlhe arms 42 may be spaced according to different thickness of doors which may be encountered: for example, two arms would be spaced apart one-half the difference in thickness of inside doors and outside doors to maintain the mortises in relative positions, and the arm nearest the proximal margin of the body Ill would be placed normal to the face plate I2 when placed upon the thicker door. the other arm being then left in extension'of'the template.

For the same purpose jamb gage arms 45 are placed at the distal corners of the body I0, being pivotally mounted in corner notches 41 inthe plates I1 on pins held in the plates I2 and 25, so as to swing in a plane parallel to the face of the plate I2. When in positions normal to the distal margins of the body IB, the arms 46 will' extend beyond'these margins a, distance of onehal-f the difference in thickness of two different doors, be-

ing placed in this normal position for placing the template on jambs o f the greater thickness, as shown in Fig. 4, and being extended above land below the template when operating onv the thinner jambs. v

In operation the templateis always gaged fromthe striking side of a door and fromv the" struck side of a jamb. v The proper size and shape ofthel general opening through the body Il] having been established either as vshown or by substitution of pressed into the woodwork, the gate 2l is moved into position to close the openings I5-28, and the depth plate Il is folded back to the plane ofthe body l0. A routing tool may'then be applied to the template, withthe cutter extending through the remaining open portion of the general ope-ning, the guide of the tool engaging the sides of the open portion, and the face of the tool pressed against the plate 26. The mortise may also, of course, be cut with a chisel guided in the same manner.

The jamb mortise is cut in the same way, positing the template with reference to the jamb stop either by the distal margin of the body l0 or by the gage arms 46 as may be required, and by pressing the spurs into the woodwork. The gate 2l is moved to uncover the openings |528, and the depth plate Il is folded upon the body l0. A routing tool may then be applied to the outer face of the depth plate Il, and will rout a shallow mortise differing in depth from the door mortise by the thickness of the plate l l and suitable for a striker plate instead of the relatively heavier lock plate.
